I got my Wilson .223 headspacing gauge from Sinclaires today (I really love the whole Brownells company — I ordered it on Sunday and here it is on Wed
)
Did a quick check on my brass and found that my Dillon FL resizer and my RCBS SB resizer both headspace fine. haha
As for why I have two resizers, I bought the RCBS dies first, but picked up the Dillon at my LGS to see how its taper crimp die worked (also the carbide expander ball is a nice feature). Turns out that I get perfectly functional reloads with no crimp at all...so I guess I'll just hold onto the Dillon dies for when I finally break down and buy a progressive press. hahaha.
